The process is now general enough that you could have booted
from boot.iso, pxeboot, usb stick or other image, which contain
only enough to boot, and not enough to perform rescue operations.
In those cases you need to find the rest of the rescue software,
which might be on nfs, http, ftp, CD/DVD, harddisk, ...
Except that if the kernel can read your CD drive, anaconda will check there
first for the rescue media. If it can't find it is when you get asked, so
something is up with this person's system in that the kernel may not be able
to read the CD drive once booted.

Re-load the install CD/DVD, which contains everything needed for
rescue mode. Rescue mode should proceed. [You might have booted
a boot.iso CD-ROM in order to get a recent Linux kernel, but still
have the rescue software on another platter (which might be older,
for instance.)]

The ability to use an install CD/DVD for rescue mode is new.
No it's not. "Rescue" mode is achieved by passing "rescue" to the
kernel
argument line at boot time. Anaconda will see that and launch into rescue
mode. ANY boot media can lead you to rescue mode.
The ability to use the rescue CD-ROM as an installer also is somewhat
new.
No it's not. You've just about always been able to just type "linux" at
the
rescue boot prompt to get to the full installer. The default does "linux
rescue" to invoke the rescue mode. The rescue media just includes enough
anaconda to run rescue, and defaults to passing "rescue" to the installer.
